Abstract:
A shaped metal container such as a can is uniformly electrocoated in an inverted position by the insertion of an electrically conducting nozzle therein through which coating material may flow into the interior of the container while an electrical potential is maintained between the container and the nozzle. The nozzle is shaped to direct flow of the material into the corners of the container as the nozzle is inserted and to maintain a transient bath type mode after the nozzle is inserted into the container. Coating material is delivered at a flow rate which permits the can to remain full in an inverted position. When the nozzle is removed the container empties without further mechanical operations.
